He's pretty tough. I actually had to back up and use some throwing daggers to knock him down because it was taking to long to hit/roll/hit/roll.
Drops a potentially good item depending on what kind of character you want to play.
I'll spoiler it just in case you want to figure out the drop yourself: A sword with lightning effect. Scales C Rank with your Faith. I believe 10 Str 9 Dex requirement? Maybe 11/9 respectively. The fire sword you can get a little later outclasses it completely unless you're going for a Faith build. --- http://i.imgur.com/ZhLrT.jpg http://i.imgur.com/H6Frl.jpg
